End to end
Messages and calls are encrypted on your device.
Chat and calls, comingIn closed testing
Chats and calls only the people in them can read.
KolChat is the messenger being prepared for KolHive. Text, voice notes, photos and files are encrypted on your device before they are sent, and voice and video calls go from device to device, encrypted end to end. The encryption follows the Signal protocol design and has not had an independent audit yet. KolChat is not public yet; it will use the same account as KolHive and KolWrite.
Groups and channels
Groups of up to 1,024 people, communities and channels.
Meetings from a link
Up to 100 people, joining from the app or a browser.
AI on your terms
Search runs on the device; answers use the AI you pick.
What the server can and cannot see
A messenger is only as private as what its server can read, so KolChat states it plainly.
Never
Message text, photos, files, voice notes, call audio and video, meeting transcripts and your encryption keys.
To deliver messages
Who you talk to and when, group names, photos and members, and your devices' IP addresses.
Signal protocol design
The encryption follows the Signal protocol design. It has not been independently audited yet, and we say so.
One account
Sign in with the same account you use for KolHive and KolWrite.
Meetings, search and AI
The parts that usually need a server, designed to keep your words on your device.
Record and transcribe
Turn on Record and transcribe in a meeting, and the transcript is made on your device.

Decisions and action items from the meeting, as a cloud extra that uses AI credits.
